Welcome to Making Templates101! First make a four
inch grid. (or use 1" ruled graph paper) Draw a line connecting the top left corner
to the mid bottom point. Make another line from the mid bottom point to the upper right
corner. Cut out the 3 sections and lay these on your chosen template material (Mylar, cardboard, etc)...ADD
1/4 inch on all sides....and cut out your templates!

Start by laying your large triangle template atop the
Color 3 5" x 20" strip. Trace around it once, then flip,
trace, flip, trace, flip, trace, until you have four base triangles. Cut these out, using a rotary cutter and ruler...

Then lay your left side triangle template on the
Color 2 6" x 20" strip, trace around it. Flip, trace, flip, trace, flip and trace
to give you four of that side triangle. Then lay on the right side triangle template and do the
same, trace, flip, trace, flip, trace, flip and trace to get four of those.
